Deleting tracks via python plugin

Software
1

I am trying to clean the PCB at the beginning of my python plugin by deleting all tracks.
When I do:

for track in GetBoard().GetTracks():
     track.DeleteStructure()

KiCAD works for a couple of seconds and then just crashes without any messages. I also tried

for i in range(len(board.GetTracks())):
        board.GetTracks()[-1].DeleteStructure()

and got the same result.

Running it from the KiPython console seems fine, however.

Can anyone tell me why this is happening?
I am using 6.0.0 on linux mint.

Can you give us more details on which version of Kicad you are using? I’m not really familiar with Python or using it in Kicad, but knowing which version you’re using will let people help you more quickly.

Goto Help → About KiCad and paste that info into a reply. Also, do you have a small test PCB that you could post as well which shows this problem? Or post the PCB itself if it’s not anything secret? You might have found a bug…

Sure, thanks for the reply.
I actually found that the demo scripts can lead to a crash too. I opened an issue on GitLab:

and it seems like there are even fixes committed now. Pretty cool.
I still need to try them, however.
